Collagen XVI is integrated tissue-dependently into distinct fibrillar aggregates, such as D-banded cartilage fibrils and fibrillin-1-containing microfibrils. In skin, the distribution of collagen XVI overlaps that of the collagen-binding integrins alpha 1 beta 1 and alpha 2 beta 1. Basal layer keratinocytes express integrin alpha 2 beta 1, whereas integrin alpha 1 beta 1 occurs in smooth muscle ce
It is demonstrated how microemulsions can be used as model systems to study a range of fundamental liquid state phenomena. By carefully characterizing a single ternary system it is possible to obtain both a qualitative understanding and a quantitative description using the concept of the curvature energy of the surfactant film at the water-oil interface. We demonstrate the approach on the followin
Expression of the metastasis-associated protein, ezrin, in over 5,000 human cancers and normal tissues was analyzed using tissue microarray immunohistochemistry. Ezrin staining was compared between cancers and their corresponding normal tissues, between cancers of epithelial and mesenchymal origin, in the context of the putative inhibitor protein, merlin, and against clinicopathological data avail
1 This work demonstrates that spatial distribution of understorey vegetation and gross N transformation rates in a mixed beach-oak forest is closely correlated within a distance of a few metres. The findings imply that plant diversity and productivity have a major influence on gross rates of N transformation and vice versa. 2 A geostatistical analysis was used to evaluate the spatial relationship
We evaluated the effects of different electrical parameter settings on the intelligibility of speech in patients with Parkinson's disease (PD) bilaterally treated with deep brain stimulation (DBS) in the subthalamic nucleus (STN). Ten patients treated with DBS for 15 +/- 5 months (mean, SD) with significant (P < 0.01) symptom reduction (Unified Parkinson's Disease Rating Scale III) were included.
The prognostic impact of body mass index ( BMI) in patients following acute myocardial infarction ( AMI) may be altered by neurohormonal blockade. Methods: The impact of neurohormonal blockade on the association between BMI and mortality was examined in 5548 patients following AMI ( CONSENSUS II), 50% receiving enalapril and 7% beta- blockade, and in 4367 patients with coronary artery disease ( CA
The objective of this review is to examine the published data regarding quality of life (QOL) in patients with bladder cancer. Not a single, randomized controlled trial exists. Most studies are retrospective, cross-sectional, and have serious methodological flaws. There is no single QOL tool preferably used in bladder cancer. While there is no long-term data after therapy for Superficial cancer, m
Gate arrays are often presented as a convenient means for ASIC prototyping. Obviously, they can both perform the same function and therefore be built from the same behavioral description. Design development implies a process of subsequent parameter bindings, leaving steadily less freedom for the remaining implementation choices. On the other hand, the ASIC offers more place & route freedom tha
We investigate the hardness of approximating the longest path and the longest cycle in directed graphs on n vertices. We show that neither of these two problems can be polynomial time approximated within n(1-epsilon)for any epsilon > 0 unless P = NP. In particular, the result holds for digraphs of constant bounded outdegree that contain a Hamiltonian cycle. Assuming the stronger complexity conject
The European Gaia astrometry mission is due for launch in 2011. Gaia will rely on the proven principles of the ESA Hipparcos mission to create an all-sky survey of about one billion stars throughout our Galaxy and beyond, by observing all objects down to 20 mag. Through its massive measurement of stellar distances, motions and multicolour photometry, it will provide fundamental data necessary for
Patients with contact allergy to sesquiterpene lactones (SLs) are usually hypersensitive to Asteraceae plant products such as herbal teas. The objective of this study was to show sensitizers in chamomile tea by patch testing with thin-layer chromatograms. Tea made from German chamomile was separated by thin-layer chromatography. Strips of the thin-layer chromatograms were used for patch testing SL
Estrogen and progesterone are key regulators of normal breast epithelial cell proliferation and differentiation. They are also involved in the initiation and progression of breast tumorigenesis. Several experimental studies have demonstrated that steroid hormones affect cell cycle proteins associated with tumor initiation and progression. Hormone replacement therapy (HT) is widely used to alleviat
